(PhysOrg.com) -- The ocean is a potentially vast source of electric power, yet as engineers test new technologies for capturing it, the devices are plagued by battering storms, limited efficiency, and ...

The fast-spinning, carbon-fiber-black cylinders of CycloTech’s cyclorotors are a far cry from the paddle-wheel cycloidal propellers of the early 20th century. But the principle behind this compact and ...

Cycloidal rotors employ blade elements that translate and rotate along a trochoidal path, enabling continuous adjustment of blade pitch and orientation to vector thrust in real time. This mechanism ...
